Abstract

The large data sets constituting 3D-volumes of reasonable resolution inflict high costs in terms of storage space and computation time. In this paper we describe an algorithm for data compression of sequences of 3D-volume projections where the projection angle increment is small and the surfaces of the objects in the volume are rendered using depth-only shading. The algorithm is based on a ray-casting method for incremental generation of such sequences. Experiments on a specific CT-volume yielded a compression factor of 32 for an angle increment of 1 degree and grid-point accuracy in object surface localization.
